Transformations in Matter and Energy Carbon TIME is an NSF-funded partnership led by Michigan State University
Human Energy Systems | Activity 4.5
Target Student Performance
Students use a diagrammatic carbon cycle model to investigate how oceans and seasons in the Northern and Southern Hemispheres affect the annual cycle and a long-term trend in the atmospheric CO2 pool.

- 4.5 Seasons & Oceans PPT
- 4.5 Seasons and Oceans Worksheet (1 per student)
- 4.5 Grading the Seasons and Oceans Worksheet
- Learning Tracking Tool for Human Energy Systems (1 per student)
- Assessing the Learning Tracking Tool for Human Energy Systems
- (Optional) Big Idea Probe: What Would Happen if We Cut Fossil Fuel Use in Half (1 per student)
- (Optional) Assessing the Big Idea Probe: What Would Happen if We Cut Fossil Fuel Use in Half
Prepare one copy of 4.5 Seasons and Oceans Worksheet and one copy of Big Idea Probe: What Would Happen if We Cut Fossil Fuel Use in Half for each student. Prepare a computer and projector for the film and 4.5 Seasons & Oceans PPT. You may want to open the videos ahead of time on your computer as they will be shown during this lesson. Make sure students have their Learning Tracking Tool for Human Energy Systems available for the end of the lesson.
This activity includes opportunities for both formative and summative assessment.
- Check for student understanding of the reading using the Questions, Connections, Questions Reading Strategy Educator Resource
- Use 4.4 Grading Global Computer Model Worksheet to check for student understanding after the activity is over.
- Check for changes in students’ predictions and strategies for predicting based on Assessing the Big Idea Probe: What Would Happen if We Cut Fossil Fuel Use in Half
- Compare your students’ summaries of what they learned and questions to the suggestions on Assessing the Learning Tracking Tool for Human Energy Systems
Watch the Pumphandle video a few times to allow students to ask questions and to check for comprehension of the many different components of the video.
